Denser, Faster Memory Challenges Both DRAM and Flash

A new memory technology can store a terabyte on a chip the size of a postage stamp.

A new type of memory chip that a startup company has just begun to test could give future smartphones and other computing devices both a speed and storage boost. The technology, known as crossbar memory, can store data about 40 times as densely as the most compact memory available today. It is also faster and more energy efficient.
